The PCI-443 Single Channel Digital Oscilloscope and the PCI-444 Dual Channel Digital Oscilloscope have 12 bits of resolution, a 20 MHz bandwidth, and a sample rate up to 40 MSPS. These PC expansion board oscilloscopes have extensive triggering features including burst mode, variable trigger channel gain, trigger filters, an "Arm" mode, pre/post trigger information, and an optional video trigger circuit. These digital storage oscilloscopes (DSO) also have ten vertical ranges, AC/DC coupling and an offset control. The DSO sample rate can be controlled using the internal clock circuit or via an externally applied clock.

High Voltage Power Line Disturbance testing is easily accomplished with these digital storage oscilloscopes’ combination of resolution, bandwidth, speed, probe interfaces, and pulse analysis capabilities.

These digital storage oscilloscopes have the specifications and features necessary for measuring video and HDTV signals, digitally modulated communications signals, motor test signals, I/Q vectors, laser detector signals, ultrasound responses, and many others. And, a DSO such as the PCI-443 or the PCI-444 is a valuable test asset in an ATE system. Pictured on the left is the result of a high voltage (HV) impulse test performed on a switching power supply. Using three of the pulse analysis functions of the BenchTop™ Plus software package, the test engineer easily determines the important parameters of the pulse. The test uses the guidelines developed by the IEC to verify that the UUT satisfactorily protects itself. Three options are available for these digital storage oscilloscopes. The Master/Slave option synchronizes the sample clock and trigger signal of multiple DSOs. Also, the Master/Slave option can be used to synchronize the DSO to one of PC Instruments’ arbitrary waveform generators. Differential inputs are another option. Many situations warrant the use of differential inputs including measuring the output of sensors and measuring "high side" voltages on motor controllers, power systems, and SCR circuits. Impedance analysis systems are easy to build by "Master/Slaving" a PCI-444 Dual Channel Digital Oscilloscope (with one single-ended input and one differential input) and a PCI-343 Single Channel Arbitrary Waveform Generator. The single ended oscilloscope input is used to measure the DUT’s voltage while the differential input is used to measure the DUT’s current via a sense resistor. And, a video trigger option, with line counting, will be available on the PCI-444 in the future.
